Solar generation and benefit model

Model a chosen period from array size, local peak sun hours, system losses and entered tariffs.

Your inputs

Your plan

Complete the inputs to see the result.

What this assumes

  • Enter local average daily peak sun hours for the chosen period from a public solar resource. These are equivalent full-output hours, not daylight hours.
  • Generation equals array kWp times peak sun hours times days, reduced once by system losses. Shading, orientation, inverter clipping and seasonality need site-specific review.
  • This scenario excludes batteries, export limits, financing and degradation. Self-use is your assumed fraction of generation, rather than a measured load match.
  • Costs use the rates you enter, before tax. Currency selection labels amounts and does not convert them.

How it works

  1. Put in your numbers

    Use your own rates, times and measurements.

  2. See your answer straight away

    It works it out as you type.

  3. Copy or print it

    Send it on, or keep it with the job.

How to use solar generation and benefit model

Model a chosen period from array size, local peak sun hours, system losses and entered tariffs.

  1. Enter array nameplate capacity (kwp) and the other measured inputs.
  2. Check the units and the assumptions below the result.
  3. Review the result, then copy or print the plan. Signed-in managers can save a private customer snapshot.

Tips and common mistakes

  • Enter local average daily peak sun hours for the chosen period from a public solar resource. These are equivalent full-output hours, not daylight hours.
  • Generation equals array kWp times peak sun hours times days, reduced once by system losses. Shading, orientation, inverter clipping and seasonality need site-specific review.
  • This scenario excludes batteries, export limits, financing and degradation. Self-use is your assumed fraction of generation, rather than a measured load match.
  • Costs use the rates you enter, before tax. Currency selection labels amounts and does not convert them.

Questions

Where do the input values come from?

You enter your own values. Start with array nameplate capacity (kwp) and use measured quantities, product specifications or your chosen planning assumptions.

What assumptions affect the result?

Can I save this against a customer?

Signed-in Field managers can open the Toolbox version and explicitly save the inputs and result to their private customer history.

Does this book work or place an order?

This prepares a planning result. Review the scope and use the existing job, quote, schedule or supplier workflow separately when ready.
